我确实知道 Timeout.InfiniteTimespan 在 .NET 4.0 中不存在.
I actually do know that Timeout.InfiniteTimespan does not exist in .NET 4.0.
请注意,.NET 4.0 中也存在 Timeout.Infinite
Noticed, there's also Timeout.Infinite which does exist in .NET 4.0
我正在调用这两个方法:
I am calling those two methods:
// the Change-Method public bool Change( TimeSpan dueTime, TimeSpan period ) // the Constructor of Timer public Timer( TimerCallback callback, Object state, TimeSpan dueTime, TimeSpan period )在某些情况下,dueTime 参数需要是无限的,这意味着事件不会被触发.我知道我可以简单地使用其他重载,但我觉得有些事情必须更简单.
in some cases, the dueTime Parameter needs to be infinite, which means the Event is not fired. I know I could simply use an other overload, but I feel like something has to be more simple.
我已经尝试使用 new TimeSpan(0, 0, -1) 或 new TimeSpan(-1) 作为 DueTime.*但这会引发一个 ArgumentOutOfRangeException 指向 dueTime 参数.
I already tried using new TimeSpan(0, 0, -1) or new TimeSpan(-1) as dueTime. *But that throws an ArgumentOutOfRangeException pointing to the dueTime Parameter.
是否有可能创建一个像 .NET 4.5 中的 Timeout.InfiniteTimespan 一样工作的文字?
Is it somehow possible to create a literal working like the Timeout.InfiniteTimespan from .NET 4.5 ?
推荐答案TimeOut.InfiniteTimeSpan in TimeOut 类定义为:
TimeOut.InfiniteTimeSpan in TimeOut class is defined as:
public static readonly TimeSpan InfiniteTimeSpan = new TimeSpan(0, 0, 0, 0, Timeout.Infinite);其中 Timeout.Infinite 设置为 -1,因此它正在传递 -1毫秒值 部分.
Where Timeout.Infinite is set to -1,so it is passing -1 value for milliseconds part.
你可以这样做:
TimeSpan InfiniteTimeSpan = new TimeSpan(0, 0, 0, 0, -1);更多推荐
.Net 4.0 中的 Timeout.InfiniteTimespan?
